3.2 Remote On/Off Controlled mode
The PSON# signal is required to remotely turn on/off the power supply, PSON#
is an active low signal that turns on the output power rails. When this is not
pulled low by the system, or left open, the outputs (except the +5VSB) turn off.
This signal is pulled to a standby voltage by a pull-up resistor internal to
the power supply.
3.3 Regulation
The cross regulation defined as follows, the output regulation should be within
the specified range.
Load
Light Load
Typical Load
Full Load
3.4 Rise Time
DC output rise time is less than 20 mS at nominal line and full load.
3.5 Hold-up Time
DC +5V, +3.3V ,12V output maintains at least 16mS after power off which hold
within 60% loads under 230V/50Hz condition.
3.6 5VSB
5VSB is requierd for the implementation of PS-ON described above. 5VSB is a
standby voltage that may be used to power circuits that require power input
during the powered-down state of all power rails. The 5 VSB pin should deliver
5V ± 5% at a minimum of 3.0 A for PC board circuits to operate. Conversely,
PC board should draw no more than 3.0A maximum form this pin. This power
may be used to operate circuits such as soft power control.
3.7 PG-OK
PG-OK is a power good signal and should be asserted high by power supply to
indicate that the +5 VDC and +3.3 VDC outputs are above the under-voltage
thresholds of the power supply. When this signal is asserted high, there should
be sufficient mains energy stored by the converter to guarantee continuous
power operation within specification. Conversely, when either the +5VDC or the
+3.3VDC output voltage falls below the under-voltage threshold, or when mains
power has been removed for a time sufficiently long so that power supply
operation is no longer guaranteed, PG-OK should be deasserted to a low state.
See Figure 1 for a representation of the timing characteristics of the PG-OK,
PS-ON, and germane power rail signals.
